This paper presents an ongoing project for augmenting acoustic instruments with active acoustics. Active acoustics are defined as audio-rate vibration driven into the instruments physical structure, inducing air-borne sound output. The instrument’s acoustic sound is thus doubled by an electronic soundscape radiating from the same source. The article is centered on a case study on two guitars, o...

JDMS, Volume 1, Issue 4, October 2004 Page 225–233 © 2004 The Society for Modeling and Simulation International Acoustics is an important consideration for realistic agent behavior in land combat, entity-based simulation models. This research describes basic approaches to representing and applying outdoor sound with limited discussion of the evolving field of indoor acoustics in such simulation...

Room acoustics has a scientific interdisciplinary concept which will be further developed in future. During the last century, several dimensions of the overall listening impression in concert halls were identified which show a good correlation with corresponding objective measurement data. It can be summarized that the three most important factors (loudness, reverberance and spatial impression)...
